This Cheesy Spinach and Chicken Mac is less like a traditional mac and cheese and more like a casserole. It’s one of my favorite comfort foods to make. It’s just as delicious the next day as all the flavors mingle and meld together, or you can make it in advance and keep it in the freezer for days when you don’t feel like cooking.
The Creamiest Mac and Cheese Gets a Spinach and Chicken Upgrade
There are nights when all I want is a pan of something bubbling and cheesy, nothing fancy, just pure comfort. That’s when I pull out this spinach and chicken mac and cheese. It’s not quite your typical baked mac and cheese. With added protein and spinach it’s an entire meal.
I’ve made plenty of macaroni and cheese recipes in my life, but this one? It holds its own. I swapped part of the pasta for shredded chicken and fresh spinach, which keeps it from feeling too heavy but still feels like the cozy bowl you want to curl up with.
The sauce doesn’t start with flour like most. Instead of making a roux, cream and milk simmer down slowly with onions and garlic until it’s thick enough to cling to the pasta. Once you melt in sharp cheddar and parmesan, it’s hard not to dip a spoon in before it even hits the oven.
And then there’s a little heat. Just a dash. Not enough to scream buffalo chicken mac, but enough to perk up the flavors. You can always leave it out for a milder version.
You know what else I love about this recipe? It’s flexible. Got leftover roasted chicken? Perfect. A rotisserie bird from the store? Even easier. Half a bag of spinach in the crisper, about to wilt? Toss it in. This is my kind of clean-out-the-fridge dinner.
When I serve this chicken mac and cheese casserole, I usually add something fresh on the side. A simple Greek cucumber salad cuts through the richness. Or, if it’s peach season, I’ll make a quick tomato and peach salad for that sweet-salty balance.
Ingredients Notes
(See the recipe card for the full list and measurements.)
- Pasta – short noodles like penne, bowtie, or elbow work well.
- Spinach – fresh or frozen, it cooks right into the sauce.
How To Make Cheesy Chicken Mac
Step One: Prepare Pasta
Step Two: Start Sauce
Cook onions in butter and olive oil, add garlic and cook an additional minute. Warm milk and cream in the microwave and add to the onion mixture. Reduce the heat to low and simmer until it has reduced, then add seasonings.
Step Three: Add Cheese
Step Four: Bake Casserole
Bake for 45 minutes or until the sauce bubbles at the edges and the top turns golden brown.
This mac and cheese with chicken feels like the best of both worlds: a pasta bake with just enough veggies to pass as balanced but still creamy, cheesy, and satisfying. Leftovers are even better, which means lunch the next day is already handled.
